Change this to

#if __FreeBSD_version < 1000000
    p->bitmap = (unsigned long *)kmem_alloc(kernel_map, p->size);
#elif  __FreeBSD_version < 1200080
    p->bitmap = (unsigned long *)kmem_malloc(kernel_arena, p->size,
M_WAITOK | M_ZERO);
#else
    p->bitmap = (unsigned long *)kmem_malloc(p->size, M_WAITOK | M_ZERO);
#endif

That said, it's not clear to me why this allocation doesn't use
malloc(9), then no #if's would be required across different versions of
FreeBSD.
